Define your infrastructure as type-safe objects in code

Declare what your application needs directly in Go, and Encore automatically provisions it across local development, preview environments, and production.

Automated local infrastructure

Encore automatically provisions all local infrastructure: databases, Pub/Sub, caches, and more.
No Docker Compose. No config files. No manual setup.

Explore your app's architecture, APIs, traces, and databases in real-time

An SDK you and your AI will love

Encore provides structured patterns and built-in infrastructure guardrails, so you and your AI can build production-grade distributed systems with confidence.

✓

Infrastructure Generation

Robust patterns for integrating databases, pub/sub, cron jobs, and more. Encore runs everything locally for you and provisions it seamlessly in preview and production

✓

MCP for Introspection

Built-in MCP server lets AI understand your services, APIs, schemas, and traces

✓

Standardization & Guardrails

Encore's compiler ensures generated code follows established service structures and API conventions

MCP Server →AI Instructions →Quick Start →

Turn functions into APIs
with one line of code

Add the //encore:api annotation to a Go function and Encore generates all communication boilerplate at compile-time.

hello.go

✔API defined - Encore generates boilerplate at compile-time

Built-in local developer tools

From your application code, Encore automatically generates documentation and architecture diagrams, and provides distributed tracing out of the box.

Service Catalog

Service Catalog with API explorer and auto-generated docs from your Go types.

Architecture Diagrams

Real-time architecture diagrams showing services, APIs, databases, Pub/Sub topics, and their connections.

Distributed Tracing

Built-in tracing for API calls, database queries, and Pub/Sub messages — no instrumentation needed.

"Encore is our foundation for all new development. Since adopting it, we've seen a 2-3x increase in development speed and 90% shorter project lead times."

Josef Sima · Engineering Director

"Encore lets us go from idea to shipped product at least 3x faster and saves us hours of devops work every week."

Will · Co-founder

"We've reduced time spent on DevOps by 95%, and we're now on track to save $60K annually in cloud costs."

Mason Stewart · CTO

"Encore is an unfair advantage. At Pave we've moved 2x faster than we did at Monzo."

Simon Vans-Colina · CTO

"We're saving $200k+ annually compared to additional hiring. The ROI is outstanding, easily 10x."

Daniel Stocks · CTO

"You define infrastructure in your code and it's automatically spun up for you. You can go from zero to a deployed service on GCP in an hour. I don't know how else to do it."

Nilkanth Patel · CTO

"Encore's inferred infrastructure has allowed us to move at unprecedented speed. Combined with database branching in Neon, we're able to spin ephemeral environments up and down with incredible ease. Stakeholders love preview app URLs."

Justin Foley · VP of Engineering
